hi list,

My linux boots with following kernel info, 

Linux version 2.6.8-2-686 (dilinger@toaster.hq.voxel.net) (gcc version
3.3.5 (Debian 1:3.3.5-6)) #1 Mon Jan 24 03:58:38 EST 2005

Capability LSM initialized
Linux agpgart interface v0.100 (c) Dave Jones
i810fb: Unknown symbol save_vga
i810fb: Unknown symbol restore_vga

I video card is intel 810e, xserver can't start due to the error
'/dev/agpgart not found',
In fact, I have created the agpgart in /dev with MAKEDEV agpgart,
I don't know what's real cause that makes the xfree86 failed to startup, 
I'd like to know if the kernel booting message is related with xserver problem?
